If the leading scientists suggest that a mask is warranted as it helps slow down a virus, I'll do it. Valid advisor, valid reason, legit goal and little effort.

If a governor made a recommendation about a mask, likely he took advice from others. Valid reason, valid person, valid goal, little effort.
